Answer:
D. -1.2(3x-40)
Step-by-step explanation:
Multiply -1.2 x 3x and -1.2 x -40.
-1.2 x 3x= -3.6x
-1.2 x -40= 48 (two negatives cancel each other out, so it will be +48)
= -3.6 +48.
You can also automatically eliminate B. and C. because multiplying the -4 within the perenthesis would not give you 48.
A. says (3x + 40), which would give us a negative 48.
